gen.find.Min.Distance.MRCA: Finds the minimum distances between pairs of individuals...

In GENLIB: Genealogical Data Analysis

Finds the minimum distances between pairs of individuals given a set of ancestors.

Description

Returns the shortest distances (number of meioses) between pairs of probands given the matrix of MRCAs output by the gen.findMRCA function.

Usage

gen.find.Min.Distance.MRCA(genMatrix, individuals="ALL", ancestors="ALL")

Arguments

genMatrix	Matrix of most recent common ancestors, MRCAs, obtained with gen.findMRCA. Required.
individuals	Vector of proband id numbers to include. All are included by default.
ancestors	Vector of MRCA id numbers to include. All are included by default.

Value

returns a matrix

Examples

data(geneaJi) 
genJi<-gen.genealogy(geneaJi) 
matMRCA<-gen.findMRCA(genJi, individuals=c(1,29), NbProcess = 1)
gen.find.Min.Distance.MRCA(matMRCA)


# Increasing NbProcess will decrease execution time
data(genea140) 
gen140<-gen.genealogy(genea140) 
matMRCA<-gen.findMRCA(gen140, individuals=c(409033,408728,408828), NbProcess = 1)
gen.find.Min.Distance.MRCA(matMRCA, individuals=c(409033,408728))
